BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The present invention relating to an inner tangentially drivingexerciser, more particularly to an exerciser providing a moving wheelfor an exercising means to drive inner tangentially thereby lowering anoperation position and achieving the safe effect, mainly comprises adriving apparatus relatively assembled at the position of a lowercircular tangent point of an inner circle of a motion wheel toindirectly link the motion wheel through the function of an externalforce so as to allow the inner circular plane of the motion wheel to bethereby not only increasing the safety of application, but also loweringthe operation position to facilitate the cooperative applications forvarious types of exercisers.

[0003] 2) Description of the Prior Art

[0004] The design of an exerciser, a toy or a transportation meansabsolutely requires a driving wheel for making movement; for example, arear wheel of a bicycle has a wheel with an inner breadth planeconnected with a hub through spoke rods; the center of the wheel iscoaxially assembled by a passive gear through a chain or any otherdriving methods, to transmit an epicyclical couple to the wheel via thespoke rods for achieving a driving objective; or, for example, a wheeldisposed on an exerciser might have spoke rods connected with a hubtoward the center of the wheel or have a circular board body connectedwith a wheel tire frame on the outer circle, a hub connected at thecenter and similarly a coaxially jointed gear or belt wheel to transmitthrough an external force for driving the wheel.

[0005] However, the work efficiency of a transportation means and anexerciser requires different designs. For a transportation means, it isnecessary to reach the highest converting efficiency of the dynamicforce; however, the design of an exerciser is oriented to a reversedirection to lower the efficiency of the force transmission in order toincrease the degree an exerciser's force exertion so as to achieve theexercise for muscles and bones. The design of a traditional wheel uses acentral point as a supporting point and has the least resistance of themoment of force and that is not suitable for being applied onto anexerciser. Furthermore, the inner breadth plane of the wheel connectswith the spoke rods to install elements and has an axel center.Therefore, after being applied to any transportation means or exerciserand the main body structure is connected with the wheel, the center ofgravity of the platform will be either too high or not able to meet thecooperative requirement of various new style designs.

[0006] Furthermore, since the conventional wheel has spoke rods, theuser's foot might be injured due to the tangentially press of the spokerods or the toe tip might be twisted due to accidental insertion betweenthe spoke rods when there is a miss during the exercise operation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] The present invention of an inner tangentially driving exerciserprovides an exerciser using an inner circle tangent point totangentially move the external portion of a wheel so as to design ahollow inner breadth plane on the wheel and to facilitate the loweringof the center of gravity.

[0035]FIG. 1 shows the driving method. As indicated, the exerciser ofthe present invention mainly comprises a driving apparatus (1)relatively disposed on a circle tangent point at the lower aspect insidethe interior portion of an inner circle of a motion wheel (4). Two sidesof the driving apparatus (1) are respectively disposed with a diagonaleccentric shaft (15) that connects outwardly with a pedal board (10);the eccentric shaft (15) is fixedly installed on a rotary disk (13). Theentire driving apparatus (1) is fixedly fastened by an inner hoop body(2). On the inner hoop body (2), the upward positions at ten o'clock andten minutes past the hour are respectively disposed with a railingdevice (21). The indirect contact between the inner hoop body (2) andthe motion wheel (4) functions a link wheel frame (3) disposed with themotion wheel (4). Three supporting points (P1, P2, P3) are formedbetween the link wheel frame (3) and the inner hoop body (2) to define aplanar principle thereby allowing the inner hoop body (2) to efficientlyand precisely position at the center of the inner circle of the motionwheel (4). Therefore, the user treadles the pedal board (10) to make thedriving apparatus indirectly provide the motion wheel (4) a dynamicforce to drive epicyclically. Furthermore, a saddle seat (30) isdisposed on the top portion of the motion wheel (4) relative to theinner hoop body (2) for the user to make figure operation, take atemporary rest during the exercising procedure, clamp it by two legs anduse it as a seat pad so as to define a brand new exerciser.

[0036] Referring to FIG. 2, a railing wheel (211) of the railing device(21) uses a circular tangent method to tangentially press the inner webportion of the link wheel frame (3) and is movably fastened to arelative position on the inner hoop body (2) by a shaft hole (212), asalso indicated in FIG. 1. The tangential press of the railing wheel(211) allows the inner hoop body (2) to make even friction therebyefficiently maintaining in the interior portion of the center of themotion wheel (4) and aligning with an invisible central point so as toprevent the inner hoop body (2) from deflection; furthermore, therailing wheel (211) moving in the web portion of the link wheel frame(3) also assures that the inner hoop body (2) won't deflect and staggerthe link wheel frame (3). In addition, the rail device (21) can beindirectly and movably fastened on the inner hoop body (2) (not shown)via a wheel frame (214) by using the circular surface of a lateral guidewheel (213) to tangentially slide on the inner lateral side of the linkwheel frame (3) for railing applications of other kinds of elements.

[0037] Referring to FIG. 3, the driving apparatus (1) of the presentinvention is mainly assembled by two lateral rotary disks (13) disposedwith two eccentric shafts (15) at 180 degree diagonally on the outersides. The eccentric shafts (15) receive an external force to transmit adynamic force, such as a pedaling force for a bicycle. As indicated in abird's eye and cross-sectional view, it is obvious that the drivingapparatus (1) of the present invention basically comprises a drivingshaft (14) movably fastened through an inner circular hole (22) disposedat the center of the inner hoop body (2); the rotary disk (13) and thedriving shaft (14) are fixedly jointed for assembly; the center of thedriving shaft (14) links a driving wheel (11) disposed with a engagingplane (12) on the outer circular surface thereof. A unidirectionalengaging apparatus (16) is disposed between the driving wheel (11) andthe driving shaft (14) to act as a unidirectional shaft bearing forone-way driving. The engaging apparatus (16) allows the eccentric shafts(15), for example, a treadle board or a rocker rod to be activated by anexternal force, to transmit a dynamic force toward the driving shaft(14) unidirectionally, and indirectly transmit the dynamic force towardthe driving wheel (11) via the unidirectional engaging apparatus (16) tomake the engaging plane (12) thereof indirectly mesh the motion wheel(4) to output the transmitted dynamic force.

[0038] After the two eccentric shafts (15) are alternatively pedaled torotate and with enough driving inertia, the unidirectional engagingapparatus (16) make the driving shaft (14) and the driving wheel (11)release unidirectionally to avoid the inertia force from the drivingwheel (11) to reversely transmit toward the driving shaft (14) therebyallowing the user's foot to obtain a static rest.

[0039] Referring to FIG. 4, the driving apparatus (1) meshes in africtional method, wherein the entire driving apparatus (1) is movablyfastened onto the inner hoop body (14); the rotary disk (13) receivesand transmits the dynamic force obtained by the eccentric shafts (15)toward the driving shaft (14); then the driving shaft (14) transmits theepicyclical and dynamic force to the driving wheel (11) thereby make theengaging plane (12) move frictionally to a friction ring (31) disposedin the web portion of the link wheel frame (3) received in the interiorportion of the motion wheel (4). The friction ring (31) is made offriction-resistant material capable of receiving a frictional material,such as frictional fabric or rubber material.

[0040] Referring to FIG. 5, an inner annular cog (17) is disposed in theweb portion of the link wheel frame (3) disposed in relation to themotion wheel (4) of the driving apparatus (1) of the present inventionand is engaged by a mesh cogged ring (18) disposed in the drivingapparatus (1). Similarly, the eccentric shafts (15) transmit the dynamicforce to the driving shaft (14) via the rotary disk (13), output thedynamic force toward the mesh cogged ring (18) and then indirectlytransmit the driving dynamic force toward the motion wheel (4) throughmeshing the inner annular cogs (17). This method specifies theepicyclical opposite relationship thereby facilitating the applicationof transmitting heavier load.

[0041] Referring to FIG. 6, the driving apparatus (1) of the presentinvention adopts the method of enlarging the epicyclical velocity byusing an enlarging mechanism to multiply the rotary speed obtained bythe driving shaft (14) as it reaches the output end. The mechanism is alapped gear set mainly comprising the driving shaft (14) movablyfastened by the inner hoop body (2) in a same way and externallyconnected with the symmetrical eccentric shafts (15) through the rotarydisk (13). The interior portion of the driving shaft (14) connectsfixedly with a driving gear (5); the outer periphery of the driving gear(5) further drives a lapped gear (51) with a smaller wheel diameter; thelapped gear (51) synchronously links a bigger gear and then reverselymeshes a passive gear (52) which is coaxial with the driving shaft (14)but has no active relationship. The passive gear (52) drives a spinningdisk (50) to output the dynamic force to the engaging plane (12). Theengaging plane (12), as shown in FIGS. 4 and 5, indirectly transmits thedynamic force to the motion wheel (4). To intermittently stop pedalingand avoid the spinning disk (50) to reversely feedback the inertiaforce, a unidirectional engaging apparatus (521) divides the spinningdisk (50) and the passive gear (52) for releasing the reverse inertiaforce. Furthermore, a shaft bearing (53) functions to separate andeliminate the rotary relationship between the passive gear (52) and thedriving shaft (14).

[0042] Referring to FIG. 7, in order to enlarge the epicyclical velocityat the output end, the driving apparatus (1) of the present inventionadopts an enlarging method of a planet gear (61) which is also movablyfastened by the inner hoop body (2) in the same way. An inner coggedring (63) is horizontally disposed in the interior portion of the innerhoop body (2) as a fixed ring body. After the eccentric shafts (15)drive the driving shaft (14) to rotate, the rotation first drives aplanet disk (6) with a plurality of transverse planet gears (61)disposed movably and vertically to mesh the inner cogged ring (63) onthe outward side and a sun gear (62) toward the central point. Afterbeing multiplied by the driving shaft (14) and all the gears, therotation speed of the sun gear (62) increases the epicyclical velocityin multiplication. Similarly, the spinning disk (60) outwardly transmitsthe epicyclical dynamic force to the engaging plane (12); as the same,the motion speed of the engaging plane (12) obtains the circumferentialspeed through multiplying the epicyclical velocity of the sun gear (62)by the Ludolphian number π. In order to prevent the feedback of thedriving inertia force, a unidirectional engaging apparatus (621) isdisposed between the sun gear (62) and the spinning disk (60) as well toachieve the function of unidirectional engagement via a unidirectionalengaging apparatus (621).

[0043] The planet gear (61) is capable of not only enlarging theepicyclical velocity of the sun gear (62) in high multiplication, butalso using the planet disk (6) to connect with a plurality of planetgears (61) via the bisection angles. Therefore, the crossed and inwardcentral points of all the planet gears (61) are also located on thecentral line of the driving shaft (14) such that during the forcetransmission, the evenly distributed planet gears (61) make the branchforce evenly focus at the shaft center of the driving shaft (14) toavoid the loss of declined angles caused by declination therebytransmitting outwardly more complete dynamic force.

[0044] The structural design of using the planet gear (61) of thepresent invention to reversely enlarge the sun gear (62) makes thedriving shaft (14) bear more couple; in other words, it is necessary tohave more couple in order to enlarge the speed at the terminal end.Therefore, the action force exertion of an exerciser is more forceconsuming.

[0045] Referring to FIG. 8, on the exerciser of the present invention,the eccentric shafts (15) disposed on the driving apparatus (1) rearwardconnect with a left and a right pedal boards (71, 72); the two pedalboards (71, 72) and two eccentric shafts (74, 75) disposed on an innerspinning disk (77) at the rearward thereof form a principle of aquadruple crank mechanism that moves in parallel. When the userseparately treadles the pedal boards (71, 72), the driving apparatus (1)transmits the dynamic force to the motion wheel (4) as well for drivingforwardly. In addition, a driving wheel (73) is disposed on the outerperiphery of the inner spinning disk (77) at the rear end; a spacingring (76) spaces the epicyclical velocity between the motion wheel (4)and the spinning disk (77). The radius of the eccentric shaft (15) ofthe driving apparatus (1) equals the radius of the gyration of theeccentric shafts (74, 75) at the rear side such that the circumferentiallines (150) of the gyration are the same thereby ensuring the parallelmotion of the quadruple crank mechanism. Furthermore, the function ofthe spacing ring (76) is to space the motion wheel (4) and the drivingwheel (73) according to their different epicyclical velocities therebyavoiding the frictional interference.

[0046] Referring to FIG. 9, the eccentric shafts (15) of the exerciserof the present invention are disposed on the same angular positions andassembled through a rectilinear and overlapping relation to be providedfor other kinds of applications.

[0047]FIG. 10 shows the application, as indicated, the eccentric shafts(15) are symmetrically and coaxially disposed on the rotary disk (13)and connect with a pedal board (81) having a unshaped straddle slot(82). To the rearward, the pedal board (81) is disposed with adeflection wheel set (83) having a left wheel (831) and a right wheel(832). Therefore, the user stands thereon to treadle the pedal board(81) to form a proceeding force via the angular turning of the eccentricshafts (15). As the same, the driving apparatus (1) uses the function ofthe link wheel frame (3) to indirectly drive the motion wheel (4).

[0048] Through the method of treadling the pedal board (81), the rearaspect of the entire body steers via the deflection wheel set (83), asindicated in FIG. 11. Through the left wheel (831), the right wheel(832), a wheel holder (830) at the center and a supporting shaft (833)disposed at the center, the deflection wheel set (83) is joined andlocked at the lower aspect of the pedal board (81). The deflection wheelset (83) is of a regular roller skating shoe; when it is stepped andpressed downwardly, the left wheel (831) deflects downwardly; with thesupporting point function of the circular center of the supporting shaft(833), the wheel holder (830) deflects to the left thereby obtaining asteering application during the proceeding procedure.

[0049] On the upper surface of the pedal board (81), a resilient andauxiliary pedal board (84) is disposed for resilient application andindirect leg treadle. A resilient body (841) is disposed at the loweraspect of the auxiliary pedal board (84) to increase the assistance of aresilient reaction. Therefore, when the user treadles and at the instantwhen the front aspect of the pedal board (81) is driven upwardly, theabsorbing function of the resilient body (841) allows the user to selectthe treadle method of exerting a pre-pressured and opposite reactionforce to form various figure operation.

[0050] As indicated in FIG. 12, the eccentric shafts (15) of the presentinvention are disposed coaxially on the left and the right sides therebymaking an assembly of a sway pedal board (91) so as to form a swayunicycle (9). A saddle seat (92) is assembled at the upper aspect of themotion wheel (4) via the inner hoop body (2) as well; the link wheelframe (3) is also activated by a driving apparatus (1) and theunidirectional engaging apparatus (16), as shown in FIG. 3, is disposedin the elements relatively linked by the driving apparatus (1).Therefore, the formed structure allows the user to treadle at a lowercenter of gravity. When the pedal board (91) is balanced, the user's legportion sways rearward to achieve a very difficult technique applicationof swaying and driving forwardly.

[0051] The pedal boards (91) extend rearward to form extension arms (93)disposed respectively with a swing wheel (94) capable of freelydeflecting. Therefore, the swing wheels (94) touch the ground in africtional application to allow the user to stand on the pedal board(91) and twist the waist and the leg portions oppositely to drive theswing wheels (94) and the motion wheel (4) to achieve a driving functionof twisting and tangential movement thereby providing more kinds offigure operations.
